it is important 'that that portion of the fastener which is carried by the body of the ear contain no mechanism which is likely to get out of order, because the inside of the sheet metal piste 4f is usuely Concealed behind the npholsterlif' or other interior finish of the enr. it is sise i'iighiy ciesirnble that, as shown, there ee little or no projection from that portion oi the fastener attached to the sheet inermi plaire so 'that the exterior of the enr may present n smooth and finished appearance.
